Do I need to use old version of gpg??

[Hwi-gyeom]

I use this package in Windows environment, and can't figure out what I should do...

According to error message, I need to use another version of gpg,

but I downloaded the latest version of gpg4win(3.1.7).....(it installed gpg 2.2.15 to me) is there and restriction on the version??

gpg=gnupg.GPG(binary='C:/PleaseGPG/GnuPG/bin/gpg.exe',homedir='./keys',verbose = 'True' )

Got invalid version line from gpg: 2.2.15
